42 CFR § 110.2 - Summary of available benefits.
(1) Payment or reimbursement for reasonable and necessary medical services and items to diagnose or treat a covered injury, or to diagnose, treat, or prevent its health complications, as described in § 110.31.
(b) In general, the benefits paid under the Program, are secondary to any obligation of any third-party payer to provide or pay for such benefits. The benefits available under the CICP usually will be paid only after the requester has in good faith attempted to obtain all other available coverage from all third-party payers with an obligation to pay for or provide such benefits (e.g., medical insurance for medical services or items, workers' compensation program(s) for lost employment income). However, as provided in § 110.84, the Secretary has the discretion to pay benefits under this Program before a potential third-party payer makes a determination on the availability of similar benefits and has the right to later pursue a claim against any third-party payer with a legal or contractual obligation to pay for, or provide, such benefits.
